Well, your issue there is that isn't an official source. The latest official version of TWRP is 3.2.1 and it's available for the Nexus 6 here: https://dl.twrp.me/shamu/. I haven't had any issues flashing Oreo roms with it.

For a moment, the entire Task Force gazed at what awaited them. You could feel it; that one, fleeting moment when you know that every single individual around you is gazing in awe at the same thing, millions of individuals witnessing and fruitlessly attempting to wrap their minds around something that defies everything they thought they knew, all in absolute unison.

Perhaps no individual was as utterly perplexed as Luz'ut'uthun. He had been one of the Chief Officers of the Task Force for many Cycles. He was not around for the second deployment, but then again, no one was. Compared to many species, human lifespans were remarkably short. However, the gaps of time between each deployment still exceeded the lifetime of most other known species in the galaxy.

And it was perhaps that fact which concerned Luz'ut'uthun the most. Having been named a Chief Officer of the Task Force, there was perhaps no other individual alive who knew more about the humans, other than perhaps the humans themselves, of course.

Perhaps, he often thought to himself.

He had spent what seemed like countless Cycles studying the humans, observing them and their planet. He saw generally how their wars began, how they were conducted, and how they ended. And he saw how they repeated, again and again. True enough, Luz'ul'uthun had a very poor view of the human species.

Violent, unpredictable, lust for conflict. It's not that they don't understand how history repeats itself; it's that they invite it. They crave war. They have an appetite for confrontation and war that can never be satiated.

Yet somehow, these violence-prone people had created a global society which flourished unlike any other in the known galaxy. Somehow, with remarkably low average lifespans, they advanced themselves faster than any other sentient species before them.

They thrive in chaos. They derive genius from it. It is what they subsist on, and for them, it is an infinite resource.

The communications transmission played over and over in Luz'ut'uthun's mind.

We know. We remember. We're ready.

In so few words, they said so much, and for the first time, Luz'ut'uthun feared the humans may know just as much about him as he once thought he know about them. His mind ran wild; an absolute jungle of questions enveloping every thought. Even so, it all boiled down to three pertinent issues:

What do they know? How do they know?

And how far have they come since?

A disturbing possibility gripped him:

What did we leave behind?

After both prior deployments, a team was left behind to remove not only all traces of mankind's past civilizations in the hope that what evolved in its place would be something more conducive to peace in the greater galactic community, but to erase all traces of the Task Force itself as well. The thought grabbed at him again:

What did we leave behind?

All of this Luz'ut'uthun comprehended in mere moments, as status reports and communications came flying it rapidly. Scans and analyses of what must've been hundreds of thousands if not millions of space-faring vessels surrounding a planet in a very particular, unmistakably defensive formation. There was no question.

They've been waiting, indeed.

Luz'ut'uthun was Captain of the Task Force Capital War Vessel One. Close behind them was the Task Force Capital War Vessel Two. And a total of two Capital War Vessels was all the Task Force had. It was all they had ever needed. During both of the prior deployments, it was quickly obvious that only one CWV was necessarily for the operation. One CWV contained thousands of larger vessels and hundreds of thousands of smaller fighters. One CWV was enough to bring the entirety of humanity to its knees in less than one full rotation of its planet. The other CWV was always just an extra measure. Until now, anyway.

The CWVs easily outsized any of the vessels the human armada seemed to have. The data they analyzed indicating that the humans were still considerably behind the technology the Task Force currently used did little to bring him any relief. In only three cycles -- in only a short amount of time -- they had advanced at a rate and to a level that was seemed to border on the impossible. The Task Force may have had the better technology, but humanity had closed the gap well enough to put up a fight, and their sheer numbers indicated that both sides knew it was a fight humanity intended to win.

Luz'ut'thun knew there was no time to waste. Quelling human advancement was the very purpose of the Task Force, only now would that purpose be difficult to achieve. As he began giving deployment orders, a crewmember approached him with information that only served to concern Luz'ut'uthun even more.

They had scanned and analyzed the red planet humanity had only recently begun to colonize at the time of the first two Task Force operations. Only now, that planet wasn't red. The images projected in front of Luz'ut'uthun looked almost exactly like the human home planet they were now approaching. The crew intelligence analyst did not need to tell Luz'ut'Thun what this meant.

They terraformed another planet.

Luz'ut'uthun approached the front of the Captain's deck and observed the battle raging before him. Explosions beyond count; destruction beyond what they ever could have anticipated. Were the humans fewer in number, it was a fight the Task Force would win, but even Luz'ut'uthun could see that this was a battle they ultimately would not win. Eventually, humanity would out sustain them.

So Luz'ut'uthun made a decision. He relayed orders to CWV2 to retreat immediately and return home.

When we lose this battle, not only will there be no one to inform the GGC of what happened, but who knows what the humans could do with the technology we leave behind.

The only problem was that a CWV cannot enter faster-than-light travel so close to the orbit of a planetary body, much less while being under fire.

Thus, this order would be Luz'ut'uthun's last. He had CWV1 oriented towards Earth and recklessly pushed forward. The humans would collapse in on his ship, giving CWV2 the opportunity to retreat and gain enough distance for FTL travel back home.

In all of his time working in the Task Force, never once did Luz'ut'uthun think his first actual encounter with humans would end in a moment of self-sacrifice to hopefully buy the galaxy more time from the humans themselves.

In his final moments, he considered the likely consequences of it all. Whatever the humans knew, it likely was enough to know that billions upon billions of their own people had been systematically eradicated as a preemptive measure of a potential threat they did not yet present.

A potential threat, Luz'ul'uthun thought. And perhaps we are the ones who made it real.

Perhaps.

If the humans knew of what the Task Force had done to their species before, if they knew how the rest of the galaxy viewed them, and what the Task Force was here to do now, then they see a galactic society inherently hostile to them; one which must be dealt with for humanity's own survival.

And in a sense, they wouldn't be wrong.

CWV1's cores were quickly destroyed once the entirety of the remaining human force collapsed on the ship. Luz'ut'uthun gave the order to self-destruct, and in doing so, he was calling upon all the individuals under his command to give their lives for the galaxy. At this point, however, it was something they were all prepared to do. The order to self-destruct isn't something made to take as many humans with them as they could, nor was it to avoid being taken as prisoners. Instead, it was intended to leave behind as little as possible for the humans to study, research and engineer. Ultimately, the GGC would be able to form a military force capable of wiping out humanity.

For now, at least, he thought. Who knows how far they will have come by the time that army has formed.

The last thing Luz'ut'uthun saw was a full view of the human home planet. Despite his prior observation missions, this was perhaps the first time he truly saw the sheer beauty of the planet the humans called home. Lush blue and green coated the gorgeous globe. For a moment, it was captivating.

Paradise has given birth to monsters.

The sequence countdown was reaching its end, and so too were the lives of everyone on board, yet the last thing Luz'ut'uthun felt was overwhelming fear for the rest of galaxy. This was only the first battle, but something told him it would be far from the last.

Humanity has realized its potential, and never before has the galaxy been in greater danger.

EDIT: Holy hell! I just woke up to see the response this story has received and am floored. I truly appreciate all the positive feedback you guys have given me. I've submitted a few stories to prompts on this sub before (not to mention stuff I write in my own spare time), but never have any of my stories blown up quite like this. So yes, fear not, Part 3 is coming today. Stay tuned! :)

EDIT 2: The subreddit has been created! Drop in at /r/KenWrites. Rather barebones at the moment, and while I will post part 4 here in this thread (and the subreddit), part 5 and onwards will continue in that sub.
